Study of the mathematical routines in the IBM System/360 FORTRAN IV and FORTRAN IV (MOD II) libraries
Julian Wang, Joan Boyar · 1978
The purpose of this study was to determine what differences exist between the mathematical functions in the IBM FORTRAN IV library and the FORTRAN IV (MOD II) library at Argonne National Laboratory. The differences between the libraries were classified into nine categories. With these results, it was possible to modify some assembler routines in ANL Mathematical Subroutine Library (AMDLIB) so that they were compatible with both the FORTRAN and MOD II libraries.
